Smoke free bars? How about smoke-free restaurants first :)
To be fair though I'm witnessing a shift the last few years, at least in restaurants/tavernas/fast-food joints. You can more easily find places to eat these days where smoking inside is not allowed.
Yeah, over here in Thessaloniki we have smoke-free places which I try to support by frequenting. I guess we know the answer to the question "how much of your population needs to do something before it becomes unenforceable?". It's 30%, the percentage of adult smokers in Greece.
Hey, you don't have to tell me, I'm still waiting for smoke-free bars. Underage drinking is enforced even less than that, but it's a much less widespread problem.
The lack of "on-premises" laws is especially of little concern, as we very rarely get public disturbances because of drunk people.
